You may encounter the VALORANT VAN 84 error when your game loses a secure connection to Riot’s servers. This issue often removes you from a match without warning and can flag you as AFK.
The error usually stems from problems with Riot Vanguard, temporary server strain during busy periods, or instability in your network. Unlike other VAN errors, VAN 84 signals that your system cannot complete Vanguard’s authentication process.
How to Fix VAN 84 Error?
Advanced Network Setup Adjustments
Fine-tune your network when basic steps do not restore connectivity. Start by disabling IPv6 on your active network adapter, since Vanguard relies on stable IPv4 routing in many environments.
Update your DNS to a public, reliable provider to reduce lookup failures. Common options include:
| DNS Provider | Primary | Secondary |
|---|---|---|
| Google DNS | 8.8.8.8 | 8.8.4.4 |
Check your network adapter drivers next. Open Device Manager, locate your network device, and install the latest driver from the manufacturer rather than Windows Update.
If you use Wi‑Fi, test a wired connection. Ethernet reduces packet loss and session drops that trigger authentication errors.
Firewall and Security Software Permissions
Security tools often block Vanguard without clear alerts. Add VALORANT and Riot Vanguard to your firewall’s allowed apps list, and enable access on both Private and Public networks.
Review third‑party antivirus or endpoint protection software. Disable network inspection or traffic filtering temporarily to confirm whether it interferes with Vanguard’s service.
Avoid permanent full shutdowns of security software. Instead, create explicit exceptions so Vanguard can authenticate without restriction.
Full Removal and Fresh Installation
Persistent errors often trace back to corrupted files. Remove VALORANT and Riot Vanguard completely, then restart your system to clear remaining services.
Download a fresh installer from Riot’s official site and reinstall both components. Launch the game only after Vanguard finishes installing and prompts for a reboot.
This process resets authentication services and restores default configurations without legacy conflicts.
